Linux inode full causes insufficient disk space for file creation

Customer can not mount storage, system exception. Login system, try to manually mount partition, reported failure. Enter the mount point, try to write a file, reported insufficient disk space, first suspect that the system disk space is full:

$ DFFilesystem 1k-blocks used Available use% mountedon/dev/xvda             33030016  10407780  226 22236  32%/tmpfs                   368748         0    368748   0%/lib/init/rwvarrun                  368748    1 368692   %/var/runvarlock                 368748         0    368748   0%/var/lockudev 368748 108    368640   1%/ Devtmpfs                   368748         0    368748   0%/DEV/SHM

Find out if there are no partitions full, see the inode situation:

$ df-iFilesystem inodes iused IFree iuse% mountedon/dev/xvda            2080768 2080768       0  100% /tmpfs                  92187       3   92184    1%/lib/init/rwvarrun                 92187      -   92149 1%    /var/runvarlock                92187       4   92183    1%/var/lockudev                   92187    4404   87783    5%/devtmpfs                  92187       1   92186    1%/DEV/SHM

The inode in the root directory was found to occupy 100%. Therefore, create a directory or file, reported insufficient disk space.

See which directories have inode usage exceptions:

$ for I in/*; do echo $i; Find $i |wc-l; Done

Locate the inode that uses the exception directory, and remove the files that you do not need to use in the directory to resolve the problem.
